Essays on Byproducts

Click Chemistry describes the biocompatible reactions that are high yielding, that are very simple to perform, have wide scope, that need no chromatography to remove their byproducts and that can be conducted in easily removable solvents. The synthesis of first triazole was reported by Arthur Michael in 1893. In the 20th century, Huisgen discovered the catalyst of copper, 1,3-dipolar cycloaddition which required the temperature of 100 degree Celsius. This reaction of copper is a highly versatile reaction which does not require any specific reaction conditions and can easily be performed with various solvents, wide temperature range and pH, ...

Chlorine is used in water treatment to reduce or eradicate microorganisms, for instance, bacteria or viruses found in water (EPA, 2011). The use of chlorine for the treatment of drinking water has significantly reduced the risks or exposures to water-borne infections or diseases. Besides, the supplies of safe or treated drinking water are paramount for the health as well as the general well-being of the public. Untreated water sources, for example, streams, boreholes, dams, wells, or rain water can harbor certain harmful or dangerous microorganisms, which when consumed may cause serious infections such as cholera, dysentery, or typhoid, as ...

PCBs Polychlorinated Biphenyls (PCBs) are chlorinated hydrocarbons with two phenyl rings. They are stable, resistant to fire and possess good insulating properties. Hence, they were used widely before their ban in 1979, in transformers, capacitors, hydraulic machine lubricants, and oil based paints, adhesives, sealants, insulating and caulking material as well as in light ballasts. (US Environmental Protection Agency [USEPA], 2013). EH&S as well as FS personnel would have to handle PCBs when they indulge in building demolition, renovation, decontamination activities or in case of emergencies such as fire and explosion. PCBs present in electrical and building materials pose a ...

Introduction

Global warming has been a very common issue to a lot of people. It had become the topic of every conference, seminars and meeting around the world. It is clear to a lot of people that global warming is no longer a prediction, because scientific studies and evidence continues to arise that the earth’s climate is changing at a very fast pace. Even though the evidence is clear, there is no certainty in every single detail of the evidence because of the nature of science. Global warming has caused a lot of change to the state of the climate for it to be noticed ...

Incinerating means burning waste or trash until what is left is ashes awaiting disposal. An incinerator is a machine used to burn waste and trash until these materials are reduced into ash. The device is constructed using heavy machinery and well insulated materials that protect heat transmission into the immediate environment. Incinerating serves to keep hazardous material from finding their way into landfills where they can harm workers in such facilities (Donohoe 2003, pp. 588). The devices produce power while in process of waste burning that can be used elsewhere. The byproducts of incineration are air and smog pollution, and ...

Introduction

One of the byproducts of urban growth and development is the waste production. As per the report of the World Bank (2013), OECD countries produce almost half of the world's waste, while South Asia and Africa are listed as the regions producing the least amount of waste. The Basel Convention defines 'wastes' as substances or objects that need to be disposed of in accordance with the provisions of national law. European Waste Catalogue shows 850 types of wastes out of which 420 types of wastes have been classified as hazardous waste. Hazardous wastes are those wastes considered to be ...

The history of the Caribbean is one that is rich with the culture or influence of many European influences. The legacy of colonialism contributed to much of the economic issues facing the Caribbean countries today. In order to understand the impact of the colonial legacy, one must first understand that colonialism takes the resources from a particular country, and utilizes it to promote the country that is colonized. In addition, it represents the expansion of a nation's power over countries and the people within the boundaries of that country to aid in the economic control over their labor, resources, and markets. ...

Abstract

Modern science and medicine have influenced the healthcare industry in many ways. Modern science believes in the intervention rather than focusing on the spiritual factors that are associated with the disease or illness. It is important that the modern medicine realizes the importance of spiritual healing. With advancements in spiritual healing over the last 3 decades, spirituality has been introduced in modern intervention. General physicians and healthcare professionals are seeking more focusing on the spiritual needs of patients. Clinical studies have found that spirituality when combined with modern medicine improves the quality of life and increases the survival rate ...
